The Z4000 is the ultimate combination of Speed, Power and Balance in Slow Pitch. Its premium composite barrel, stiff handle technology, and patented three-piece construction give the Z4000 a lighter swing weight, a massive sweet spot, dramatically reduced vibration compared to other bats, and maximum barrel flex, giving you the best possible feel when you bring the bat through the zone. With a balanced swing weight, the Z4000 is built for performance.
